Abstract

The utility model relates to a card connector which comprises an insulating base, a shell which covers the insulating base, a set of terminals, a tray, a rotating lever and a push rod, wherein the insulating base and the shell can form a plug-in card space; the set of terminals is contained inside the insulating base; the tray is movably contained inside the plug-in card space; the rotating lever is in pin joint between the insulating base and the shell and is positioned at the tail end of the plug-in card space; and the push rod is in cooperative linkage with the rotating lever. The middle position of the push rod main-body of the push rod is provided with an elastic arm which is arranged towards the direction of the plug-in card space. The insulating base, opposite to a preset movement track of the push rod, is provided with a bump. Thereby, when the tray is pushed towards the plug-in card space, the bump presses against the elastic arm on the push rod so as to tightly lock the tray. When the push rod is pressed for linkage of the rotating lever so as to let the tray be taken out, the elastic arm on the push rod simultaneously gets rid of pressing of the bump, interfering force of the elastic arm wanes so as to let the tray be taken out.
